Surgical outcome after autologous bone chips replacement in depressed skull fractures: a single center experience.

Background: Surgery for depressed skull fractures (DSFs) is always faced by multiple challenges including ideal timing, defect reconstruction and complications. Few data are available regarding the aesthetic results and patients' satisfaction following DSFs management.

Methods: A prospective non-randomized study included 59 traumatic brain injury (TBI) patients surgically treated for DSFs.

Predictive Factors for Regression versus Progression of Nonevacuated Posttraumatic Acute Extradural Hematoma.

 This study was a retrospective study conducted from October 2020 to October 2022 on 106 posttraumatic patients with acute extradural hematomas (EDHs) who were initially planned for conservative treatment. 74 patients had spontaneous EDH regression (EDHR), while 32 patients developed EDH progression (EDHP) and were shifted for surgery. The two groups were statistically compared regarding the different demographic, clinical, and radiographic factors to identify the significant predictors for regression versus progression of acute posttraumatic EDH.

Technoeconomic Analysis for Biodegradable and Recyclable Paper Coated with Synthetic Ionic PBAT for Packaging Application.

This study presents a technoeconomic analysis (TEA) for a novel ionic polybutylene adipate--terephthalate (PBAT), CPBAT, as a paper coating material, showcasing excellent water and oil resistance. This TEA determined total capital investment, operating costs, and minimum selling prices for a production capacity of 1,000 kg of CPBAT per day. The minimum selling prices of CPBAT coated on Kraft paper (CPBAT-K) and CPABT coated on starch-coated Kraft paper (CPBAT-S) are estimated to be $1.
